A consumer would learn this by having interest in the world around them and how it works beyond being slapped in the face with every warning possible (I’m looking at you, literally everything in the world which is known in the state of California to cause cancer). We don’t need cushioned guard rails on literally everything.
When was the last time you actually read a product manual? Many of them actually are full of warnings about how things fail. I have no idea about Bose headphones, I definitely threw away everything but the headphones immediately.
No we should not ban everything that doesn’t have a zero percent fault rate. This weird angry response is a symptom of this sheltered fear which comes from not understanding that the world isn’t ever going to be perfect. You make really bad decisions when you’re in denial about the impossibility of safety perfection.
